Method next_block

cranelift/codegen/src/cursor.rs:350–354

Go to the top of the next block in layout order and return it. - If the cursor wasn't pointing at anything, go to the top of the first block in the function. - If there are no more blocks, leave the cursor pointing at nothing and return `None`. # Examples The `next_block()` method is intended for iterating over the blocks in layout order: ``` # use cranelift_codegen::ir::{Function, Block}; # u

(&mut self)

    /// }
    /// ```
    fn next_block(&mut self) -> Option<ir::Block> {
        let pos = self.next_block_position();
        self.set_position(pos);
        self.current_block()
    }

    /// Get the position that a `cursor.prev_block()` call would move this
    /// cursor to, but do not update this cursor's position.
